This calculator is for personal information only and is not financial advice. It assumes a fixed APR and standard amortization. Actual loan offers may include origination fees, prepayment penalties, or variable rates not modeled here.
Real Amortization Math
Uses the standard level-payment loan formula — monthly payment, total interest, total cost match what a bank quote would show, not a back-of-envelope approximation.
Term Comparison
Side-by-side comparison across multiple term lengths (e.g. 36/48/60/72 months) so you can see the trade-off between monthly affordability and total interest paid.
Full Amortization Schedule
Month-by-month breakdown of payment, interest portion, principal portion, and remaining balance. Watch your principal grow as interest shrinks.

Real Loan Math, Side-by-Side Across Every Term
Most online loan calculators show you one monthly payment, one total cost, and let you eyeball the impact of changing the term. That is fine for a quick sanity check, but it misses the most important question: should I pick the 48, 60, or 72-month term? Our Free Loan Calculator displays four or five term lengths side-by-side at the same loan amount and APR, so the monthly-payment-vs-total-interest trade-off is visible at a glance. Pair that with the full month-by-month amortization schedule and you have everything you need to negotiate a dealer quote or compare personal-loan offers from different lenders.
For home loans specifically, use our Mortgage Calculator (handles escrow, PMI, and extra-payment modeling). For investment math, our Compound Interest Calculator shows the other side of the same coin. For everyday percentage math, our Percentage Calculator covers tip and discount scenarios. For credit-card payoff specifically, also try our Calorie Calculator — kidding, but our health tools live in the same category if you want them.
Loan vs Mortgage: Which Calculator Do You Need?
| Aspect | Loan Calculator (this page) | Mortgage Calculator |
|---|---|---|
| Typical Term | 12-84 months (1-7 years) | 15 or 30 years |
| Typical Principal | $1,000-$100,000 | $100,000-$1,000,000+ |
| APR Range (2026) | 5-28% depending on type & credit | 6.5-7.5% conventional, 30-year fixed |
| Collateral | Auto secured, others usually unsecured | Always secured by real estate |
| Extra Costs | Origination fee 1-5% | Escrow, PMI, points, closing costs |
| Use This Tool For | Car, debt consolidation, student loans | Home purchase or refinance |
Both calculators use the same amortization formula. The split is about defaults, term ranges, and what extras (escrow, PMI) you need to model.
How to Read the Amortization Schedule
1. Month 1 = Mostly Interest
On a $30,000 auto loan at 7.5% APR for 60 months, the first payment is ~$601 — of which ~$188 is interest and only ~$413 reduces principal.
2. Mid-Loan = 50/50 Crossover
Around month 30 (halfway), the interest and principal portions are roughly equal. Past this point, your payments work harder for you.
3. Final Month = Mostly Principal
The last payment on the same loan: ~$597 toward principal, only ~$4 in interest. Almost the entire amount is paying down the loan.
4. Total Interest = Cost of Borrowing
Sum of all interest rows. Compare across term lengths — a longer term means more rows, each with more interest. The trade-off has a price tag in dollars.
Loan-Shopping Best Practices
1. Compare APR, Not Just Rate
APR includes mandatory fees; the headline interest rate may exclude them. Always pivot to APR when comparing two offers.
2. Pre-Approval Before Shopping
Get pre-approved at your bank or credit union before walking into a dealership. Dealer financing is often 1-3% APR worse than a direct lender quote.
3. Avoid Longest Term You Can Afford
84-month auto loans exist; they almost always cost you. Pick the shortest term where the monthly payment is comfortably affordable — total interest savings compound.
4. Watch for Prepayment Penalties
Most modern auto and personal loans have no prepayment penalty. Some older mortgages and subprime personal loans do — read the contract before you sign.
